Did you pull the CO1 plug apart to enable the UPS power to the brakes? It should be a white two pin molex plug not on a board, but joining two loops of wire usually hanging to the right of the ADON board.

Why would the inspector go off and do that? Did yall ask him too? Crazy to me, inspectors I deal with may push a button or something if you need a third hand and ask but never interfere with a test.
